Question

Quizplus · Accepted Answer

The sympathetic branch of the autonomic nervous system is responsible for the fight or flight response, which prepares the body to respond to emergencies. This includes increasing heart rate and respiration, dilating the pupils, and redirecting blood flow to the muscles. All of these actions improve one's chances of surviving an emergency.

Therefore, options A, C, and D are incorrect as they do not reflect the actions of the sympathetic branch of the autonomic nervous system.
